This document explains how to fix a bottom sensor with to high tilt angle.

Background:
When the tilt angle is above 30 degrees the data is discarded and causes gaps in the echograms. This typically happens if the TILT-stop-knot gets loose, or slips on the cable. We need the surface detection depth (Y) to be as close to Depth sensor (X) as possible.

See the illustration for more details.

Instructions

  1. The bottom sensor TILT-stop-knot can be located as illustrated below.

It is important that there is more than enough slack on the cable below the knot, to make sure the knot takes the beating and not the connector on the sensor

When the knot is done, test it by trying to force it up- or down the cable. If you are unable to do so, the knot is secure.
